OMG. My father, a NASA pilot for most of his life, used to use exactly this as the threshold capability, when discussing aircraft autopilot systems with designers. The designers were always saying “this system can replace the pilot!” and my dad would always say, “call me when your system can ride a bike over rough ground.”
And now they’re there. Almost. Practically.

Sadly misses the mark, as the communists in China focus firmly on creating a better society for humanity, even holding birth control as a high principle, ans good diet – not the American diet! a well as electric bullet trains electricity furnished by Thorium LFTR reactors with little and benign waste products. more cars manufactured, up and running than in all America as we speak! Where does their oil come from? Well, truth is, America’s supplies will be “shared down” in the next few decades, with Chinese bidding with more highly prized, less manipulated Yuan against Americans with U.S. fiat, “Funny Money” facing even Q 3, 4, 5, “easings” by the Fed’s just to keep the country running! Unfortunately, American peons have no family farms to return to as do the Chinese workers, American peons have no electric bullet trains providing very inexpensive transportation, but they do have enormous appetites, huge bodies to fuel daily, thanks to the “Great American Corporate and Capitalist Propaganda Whore’s”
and their “Sales pitch bull Shiite”, and some still try to pay for the impossibly wasteful McMansions, so skillfully marketed as part of the American identity, yet so ridiculously impractical, unsustainable, and highly taxable! Robot bikes? Better SMART goals: Anaerobic sewage digestion by law, throughout the nation. Thorium fueled LFTR reactors http://www.theoildrum.com/node/4971 explains. Rail that runs on time runs fast, Conventional Solar/Thermal electric plans for domestic energy increases, (Spain does this now). Wind Turbine research – find a more effective SMART windmill, to serve small, sustainable, communities at their bases, independent of the “Grid”, free of transmission loses. Commuter cars that tale no oil. Super-insulations – conserve what energy we have, decrease heating/cooling, refrigeration, cooking, costs, taking less energy! Germany does this: their gas heaters generate electricity from the same dollar’s worth of fuel! Honda sells a home sized plant here in the U.S. Who knew? Techniques, and the machinery to exploit communal living! Small stand alone neighborhoods, communities sharing to survive. Electric bikes, tuck-tucks, Gardening, with GMO’s bug free, drought resistant, higher vitamin content, better taste, fast growing, short season, with both tops ans bottoms edible. Aquaculture technologies that are totally automated run on Solar power, yield greens, and fish for protein. Help the ‘Unemployables” through American know how, new technologies, and planning to re-integrate or survive as sustainable component of society.

Now I’m not sure if this was a serious comment or not… but bending your neck does not steer a bike. It might make it lean to one side or the other, but you can’t make a bike turn by just leaning it (while still keeping your front wheel perfectly straight). Try it!
